Reduced Meshing Times
BEASY contact analysis takes advantage
of the reduced meshing times and increased accuracy
of BEM to simplify contact analysis.
Both node to node and node to surface contact are supported.

BEM not FEM
BEASY's BEM technology simplifies
contact analysis as only the surfaces have
to be defined. The BEM approach is very accurate
for contact simulation since contact stress
is essentially a surface phenomenon where
stresses and relative displacements on the
contact surfaces are of paramount importance.
BEM reduces the mesh requirements compared with FEM.

|
Load Sequences
Products can be subjected to loading
sequences to simulate the in service conditions.
Load transfer characteristics as well as
detailed stress history are predicted.

Computer Requirements: Windows 95,
98, NT, 2000 or Unix Workstation.
BEASY is compatible with existing modelling tools such as PATRAN and
IDEAS.
Windows users can also use BEASY's own modelling tools.

Automatic Contact Algorithm
BEASY's nonlinear contact algorithm
automatically computes the change in position
of the contact surfaces and the resulting stress
redistribution. The constraint based contact
algorithm driving the BEASY analysis computes
the appropriate surface contact conditions (eg,
open, closed, sliding) and enforces this condition
during the iterative solution phase.

Accurate
Prediction of Contact Stresses
& Slip
|
|
 |
BEASY harnesses the power of a constraint based contact algorithm to
efficiently compute accurate results. Rapid convergence even for complex
contact geometry
|
Accurate
Wear Data
Prediction
BEASY provides the information
to optimise components for wear. Detailed
reports are provided on the contact pressure
and slip history.
